Hi,

One thing that would be super desirable
I have a bunch of clients (5 so far) that I wanna back up
however
If the tape fills up, all the remaining jobs block waiting for the
tape to be free
worst case
The first client blocks - four 4 remaing jobs block until we can
shove in a new tape
What would happen if I set my max concurrent jobs for the director up to
the # of clients I plan to backup?
Your server would experience a higher load. Allover, your backups might
run faster. Sounds good, right?
Only make sure that the tape drive doesn't start shoe shining - if all
your tape devices and spooling disks use the same SCSI bus that's easily
the case.
This seems to be generally advised against in the docs - but perhaps
with data spooling is it ok?
The point is that, without spooling, data blocks from all the currently
running blocks are shuffled on the tape, which makes restoring slower
and is, according to Kern, error prone.
With spooling, this should work. I'm doing it with a handful of clients
and, during normal test restores I never encountered problems. Just make
sure you've got enough disk space, otherwise it's more or less pointless.

p.s. Bacula totally rocks - once I got over the learning curve it is
totally amazing!
Yup.
Only some things missing, but I think we can trust Kern ;-)

Thank you very much. This is exactly what I'm looking for.
